Iwill give brainliest which equation represents a parabola that has a focus of (0, 0) and a directrix of y = 2? a. x2=−4y b. x2=−4(y−1) c. x2=−(y−1) d. x2=−y

 The correct option is: (B) x2=−4(y−1)

Explanation:

The distance between (x,y) and the focus point is:  (Distance formula)



Plug in the values; the expression becomes: 

The distance between (x,y) and the directrix y = 2: 

In parabola both distances are equal; therefore

=

Take square on both sides:



Hence the correct option is: (B) x2=−4(y−1)
